Sonic’s gluten-free menu poses a significant risk of cross-contamination, making it unsuitable for individuals with celiac disease or those with severe gluten sensitivity. Despite offering some gluten-free options, even trace amounts of gluten could lead to serious health issues for those with sensitivities. The kitchen environment at Sonic does not have dedicated procedures to completely eliminate this risk, which is a major concern for people with medical conditions related to gluten.

For those who are uncertain or have heightened sensitivity, it is strongly recommended to select a restaurant that offers a fully dedicated gluten-free menu. Prioritizing health over convenience is essential when dining out, especially for individuals who need to avoid gluten entirely to prevent adverse reactions. Always make informed decisions when choosing where to eat to ensure your safety and well-being.
